How Many Domains Are There?


Looking for the latest domain name statistics? You’re in the right place.

In simple terms, domain names are the network addresses that you type into your browser URL bar when you want to visit a website.

It’s easy to overlook their importance—most internet users use domain names every day without even thinking about it—but without them, the internet wouldn’t be as we know it today.

In this post, we’ll be sharing some eye-opening statistics that tell us more about the domain names that make up the World Wide Web. And we’ll answer all the important questions, like:

Ready? Let’s get started.

How many domains are there?

There are around 628.5 million registered domains at the time of writing. 

Of these, 43% feature generic TLDs (top-level domains), making this the largest sub-type of domain names. 

Over 37% are .com domains, making this the most common domain extension. 

And 21.5% are registered in the US, making this the country with the most registered domains.

Domain registrations over time

The number of registered domain names has been growing year over year. But registrations spiked throughout 2020, 2021, and 2022:

  • 438.4 million domains were registered as of 31 Dec 2021 (+117% YOY)
  • 201.6 million domains were registered as of 31 Dec 2020 (+21% YOY)
  • 165.96 million domains were registered as of 31 Dec 2019 

Here’s a graph that shows the total number of registered domains over time:

Total number of domain names over time

As you can see, there’s a steep upward curve, which began in the early 2000s but shot up dramatically in 2021, likely due to the impact of the global coronavirus pandemic.

The pandemic saw national lockdowns all across the world. Offices shut and consumers spent more time online. As a result, many new websites were launched to capitalize on the increase in internet traffic.

Key statistics:

  • September 2021 was the month in which the most new domain registrations ever recorded took place
  • The most domain registrations ever happened on 21 September 2021, when there were 14.5 million new registrations in a single day. 

Registered domains by TLD type

TLD (top-level domain) refers to the last part of a domain name (the bit that comes after the final dot). For example, in https://www.colorlib.com, .com is the TLD

We can subcategorize TLDs into three types: Generic TLDs (gTLD), Country TLDs (ccTLD), and New gTLDs. 

Here’s a table showing a detailed breakdown of registered domains by TLD

TLD type Registered domains Number of different extensions
Generic TLDs 270.4 million 8
Country TLDs 250.2 million 340
New gTLDs 107.9 million 1,254
Breakdown of registered domains by TLD

As you can see, there are more registered domains that use Generic TLDs than any other type of top-level domain (233.5 million), making this the most common domain name TLD. There are only 8 gTLDs, which are widely considered to be the ‘core’ domain extensions: .com, .net, .org, .gov, .int, .edu, .arpa, and .mil.

.com is the most common generic TLD with over 233.5m registered domains, and .mil is the least common with just 359 registered domains

Country TLDs (or ccTLD) are the second-most common TLD type with 250.2 million registrations. These are top-level domains that refer to countries, states, and territories and ccTLDs consist of two letters to represent the country code (e.g. .us, .tk, etc.).

There are 340 country TLDs. .tk is most common with 26.9m registered domains. And the oddly-named .xn--4dbrk0ce is least common extension with 0 registered domains.

New gTLDs are new extensions that were released by ICANN as the internet grew and demand for domain names increased. There are 1,254 new TLDs which cover fields like technology, science, etc. 

These are the least most common type with only 107.9m registrations. .xyz is most common new TLD with 11.7m domain names, while .flsmidth and .doosan are least common with 0 registered domains

How many .com domains are there?

There are over 233.6 million .com domain names, which is 37.16% of all registered domains. This makes it by far the most common domain name extension. 

Interestingly, the second most common domain name extension is .tk—the country code of Tokelau, a small territory of New Zealand in the South Pacific.

This might be surprising given that the population of Tokelau is only 1,400. But the reason for the extensions popularity is that it’s the only extension that could be registered for free. It’s also very commonly used by phishing scammers, which have harmed its reputation.

.com 233.6 million 37.16%

What is the best domain name extension?

.com is the best domain extension by most metrics. According to a study by Growth Badger, .com domains are the most memorable and the most trusted. 

Which domain name extension do people trust most?

.com received a trust rating of 3.5 out of 5 in Growth Badger’s analysis, which makes it the most trusted domain extension.

.co came a close second with a trust rating of 3.4, and .org was third with a trust rating of 3.3 

.biz was seen as the least trustworth TLD with a trust rating of 2.9

Trust rating of popular domain name extensions (1 – 5):

  • .com – 3.5
  • .co – 3.4
  • .org – 3.3
  • .us – 3.3
  • .net – 3.2
  • .blog – 3.2
  • .io – 3.0
  • .biz – 2.9

Which domain name extension is most memorable?

.com is the most memorable domain name extension with a 44% memorability score. This means that on average, people correctly remember .com URLs 44% of the time.

.co came second again with a 33% memorability score. And .blog ranked last with a score of 24%.

Memorability score of popular domain name extensions:

  • .com – 44%
  • .co – 33%
  • .org – 32%
  • .biz – 31%
  • .io – 28%
  • .us – 29%
  • .net – 25%
  • .blog – 24%

Interestingly, .biz jumped up to position 4. This suggests that despite being seen as less trustworthy than other extensions, consumers are more likely to remember it.

The upshot of this is clear: If you want to maximize value for your brand, .com is the obvious choice. But if you can’t secure a .com domain name that you like, .co is probably your next best option.

How long should a domain name be?

The perfect length for a domain name seems to be 66 characters or less, according to an analysis by Backlinko—but the shorter the better.

The SEO study found that the average domain name (URL) length for top 10 ranking results in Google was 66 characters. 

Most results on the first page were between 40-100 characters long, but the domains that ranked in position 1 had URLS that were 9.2 characters short than those in position 10, on average.

Backlinko also found that shorter URLs correlate with higher click-through rates (CTR)

What are the most abused domain name extensions?

Professional spammers and malware operators tend to use certain types of domain names. According to Spamhaus analysis, .surf is the most commonly abused domain name and has the worst reputation. 

Over 87% of the domains that use the .surf TLD are classed as ‘bad’ domains. This may include sites riddled with malware or spam.

This is despite the fact that .tk is one of the most popular TLD extensions, as we revealed earlier, and highlights that it’s popularity is largely due to its prevalence amongst spammers.
